Compile core-apps according to their own "reason" for A/B

If the core apps are not preopted in the B OTA, and REASON_AB_OTA is not
speed (by default is speed-profile) they will be interepreted/JITed.
This in itself is not a problem as we will end up doing profile guided
compilation. However, some core apps may be loaded by system server
which doesn't JIT and we need to make sure we don't interpret-only.
